There is a particular quiet in Encinitas the morning after a long storm. The gutters are still ticking, the lagoon is brown, and the beach has a new shape. It’s also the best morning of the year to learn how your house handles water, because the evidence is fresh and it won’t stay that way.
The County’s hazard-mitigation annex for Encinitas reads like a short history of those mornings. After the El Niño storms of 1982–83, it says, Encinitas beaches were stripped of vertical sand up to 20 feet deep, putting coastal bluffs and homes in jeopardy. Winter storms in 1997, 2005–06 and 2010–11 caused significant damage and required emergency protective measures, debris removal and rebuilt infrastructure. The seaside bike path along Highway 101 was undermined in 2010. Leucadia has had property losses from localized flooding, and Cardiff from coastal flooding.
What follows is a walk to take after a winter like those. It’s ordered from the roof down and from the street to the edge, so you don’t miss the quiet clues while staring at the dramatic one.
Why big winters arrive in bunches
San Diego’s rainy season starts in the fall and runs into spring. A UC San Diego study of North County sea cliffs notes that strong El Niño events are associated with unusually high winter rainfall. That’s why storm damage here tends to arrive in clusters of years rather than evenly.
The same study, which measured cliff change by airborne LIDAR between 1998 and 2004, a relatively dry stretch, still found average seacliff face retreat of about 8 centimeters per year across the Oceanside littoral cell, with a range of roughly 3 to 13. Even quiet years move the edge a little. Wet years test everything at once.
First pass: the roof line and the downspouts
Start overhead, because roof water is the largest single stream most lots handle.
- Are gutters sagging or overflowing at one corner?
- Is any downspout disconnected, crushed, or dumping onto bare soil next to the wall?
- Do splash blocks or extensions still carry water well away from the house?
- On bluff-side lots, where does the roof water end up? It should go to the street or an approved collection point, not over the edge.
California’s residential code asks lots to drain surface water away from foundation walls, with at least 6 inches of fall in the first 10 feet where the lot allows. On a narrow coastal lot that isn’t always possible, which is why swales and drains do the work instead. After a storm you can see whether they did.
Second pass: the ground right against the house
Walk the perimeter slowly.
- Puddles that lingered more than a day near the foundation
- Soil washed away from a footing, or mud splashed high on the stucco
- New cracks in patio slabs or walks, especially where they meet the house
- A gap that opened between a patio and the wall
- Water stains on the inside of garage walls or along baseboards
Take photos with something for scale. A ruler beside a crack today is worth more than a memory of it in June. If you find cracks, our foundation cracks page explains which patterns tend to mean what.
Third pass: the low spots and the street side
Leucadia and Old Encinitas carry a long drainage story, and the City has been rebuilding part of it. Its North Coast Highway 101 drainage project between Jupiter Street and La Costa Avenue has installed new 60-, 66- and 36-inch storm drain lines, with 77 new inlets planned and completion anticipated in late fall 2026, according to the City’s project page.
Public drains handle the street. Your lot still has to move its own water to the street. After a storm, notice:
- Whether water from the street or a neighbor ran onto your lot
- Whether a side yard became a channel
- Whether the crawl space vents of an older cottage sat below standing water
- Whether a garage slab took water at the door
If your older Leucadia home sits low, the earlier post on Leucadia flooding and older slabs goes deeper. Fixes for most of these sit on our foundation drainage page.
Fourth pass: slopes and retaining walls
Cardiff hillsides, Olivenhain canyons and the inland bluffs carry their own winter risks. The annex describes slope wash, the erosion of slopes by runoff, and notes that roads, roofs and paving speed that runoff up.
Look for:
- Fresh rills or small gullies in a slope
- Soil or mulch slumped at the bottom of a bank
- Retaining walls that lean, bulge, or show new cracks
- Weep holes that ran muddy, or ran not at all after heavy rain
- Wet patches at the base of a wall days after the rain stopped
A wall that weeps clear water is often doing its job. A wall that stays dry while the soil behind it is soaked, or one that has moved since last fall, needs attention. Our retaining wall repair page covers what that involves.
Fifth pass, for bluff-top owners: from a safe distance
If you live on the bluff, the edge is the part of the property you should approach least. The annex records fatal bluff failures at Beacon’s Beach in 2000 and Grandview in 2019. Don’t stand near the edge, don’t climb down, and keep guests and pets back.
From a safe vantage, and ideally from the beach at low tide with a friend:
- Note any new scarps, fresh soil fans or fallen blocks
- Look for water seeping from the bluff face
- Check whether irrigation, pool or roof water could be reaching the bluff
- Photograph the same points you photographed last year
Then turn around and look at the house. Hairline cracks that appeared this winter in walls or floors near the ocean side are worth documenting. The bluff and any shoreline structure are a separate, specialized scope involving a coastal geotechnical engineer and coastal review. The house foundation is what we look at; see bluff-top home foundations and the earlier note on how these bluffs are built.
What to do with what you find
Sort your notes into three piles.
Fix now, yourself: reconnect downspouts, clear gutters and drains, pull soil back from the stucco, turn off irrigation near slopes and the bluff until things dry out.
Watch: hairline cracks, small puddles, minor slope rills. Photograph them again in a month.
Call someone: cracks with offset or that widen, walls that moved, water inside the house, soil loss under a footing, anything new near the bluff edge.
For that third pile, a foundation evaluation documents conditions while they’re fresh. When design or a soils investigation is needed, we coordinate with licensed engineers as needed. We don’t predict how coastal agencies will respond to any proposed work, and we don’t promise any outcome from them.
A storm folder, kept every year
Keep one folder per winter: dated photos, notes on where water went, any repairs. Over a few years it becomes the clearest record you’ll have of how your lot behaves, and it’s the first thing a buyer, an engineer, or an insurer will want to see.
